Key Parameters

Substitute Part Grouping Explanation

The HTST-120-01-F-D qualifies as a substitute for the TSS-120-01-F-D based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (40)
• Number of rows (2)
• Pitch - mating (0.100" / 2.54mm)
• Row spacing - mating (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Shrouding (Shrouded - 4 Wall)
• Fastening type (Push-Pull)
• Contact finish - mating (Gold)
• Contact material (Phosphor Bronze)
• Operating temperature range (-55°C ~ 125°C)
• Material flammability rating (UL94 V-0)
• RoHS compliance (ROHS3 Compliant)

Distinguishing Parameter:

• Insulation material: TSS-120-01-F-D uses Polybutylene Terephthalate (PBT); HTST-120-01-F-D uses Liquid Crystal Polymer (LCP)
• Connector style: TSS-120-01-F-D is Board to Board or Cable; HTST-120-01-F-D is Board to Cable/Wire

Parameter Comparison

Engineering Selection Recommendations

Both TSS-120-01-F-D and HTST-120-01-F-D are Active status products manufactured by Samtec Inc. and maintain full ROHS3 compliance with identical electrical and thermal specifications. Selection between these parts depends on application-specific insulation material requirements and connector style compatibility.

The TSS-120-01-F-D with PBT insulation material is suitable for board-to-board or cable applications. The HTST-120-01-F-D with LCP insulation material is specified for board-to-cable/wire configurations. LCP offers superior dimensional stability and lower moisture absorption compared to PBT, making it appropriate for applications requiring enhanced environmental resistance. Both parts support identical operating temperature ranges (-55°C to 125°C) and maintain UL94 V-0 flammability ratings.

Frequently Asked Questions (FAQ)

Q: Can HTST-120-01-F-D directly replace TSS-120-01-F-D in existing designs?

A: Direct substitution is possible when the application accommodates the insulation material change from PBT to LCP and the connector style requirement aligns with board-to-cable/wire configuration. All critical electrical and mechanical parameters remain identical, including pitch, contact count, contact materials, and operating temperature range.

Q: What is the functional difference between PBT and LCP insulation materials in these connectors?

A: Both materials meet UL94 V-0 flammability requirements and support the identical operating temperature range. LCP provides superior dimensional stability and lower moisture absorption characteristics, while PBT offers established performance in standard environmental conditions. Material selection should align with specific application environmental exposure and dimensional tolerance requirements.

Q: Are there inventory or lead time considerations between these part numbers?

A: TSS-120-01-F-D has 774 pieces in stock; HTST-120-01-F-D has 1085 pieces in stock. Both are Active status products from the same manufacturer, indicating ongoing production and availability.

Q: Do both parts support identical fastening and mating specifications?

A: Yes. Both connectors feature push-pull fastening, 40-position configuration, 2.54mm pitch, 2-row layout, shrouded 4-wall design, and gold-plated mating contacts with identical contact geometry and phosphor bronze base material.

Q: What is the significance of MSL (Moisture Sensitivity Level) differences?

A: TSS-120-01-F-D is rated MSL 1 (Unlimited), indicating minimal moisture sensitivity. HTST-120-01-F-D is rated Not Applicable, reflecting LCP's inherent resistance to moisture absorption. This distinction is relevant only for storage and handling protocols in high-humidity environments prior to assembly.
